Remove the dead HTS_FAST_CACHE==0 code paths

HTS_FAST_CACHE has been hard-set to 1 since the coucal hashtable became
the cache index; the ==0 arms no longer even compile (they reference an
undeclared variable in cache_readex). Drop the knob, the dead arms, and
the cache_back 'use' field they read, which was never assigned.

No behavior change: the kept code is exactly what the preprocessor
selected, and the removed cache.use cleanup was a never-taken branch.
